Yes, yes, yes. I know. But my justification is that I'm struggling with
this at the moment and as a learning experience being told 'you're doing it
all wrong' is not particularly useful. ;) When I'm confident with my PHP
*then* I might start thinking about other more exciting things.

No point trying to run before I can walk, right?

Ah right. I hadn't thought of while(!feof()); another to add to my list of
things to remember next time I do it. :)

Ok. What was confusing me was that I was going to do;

$calendar[$hour]=array($first_entry,$second_entry...)

but I couldn't work out what the maximum value of $xx_entry would be and
thus couldn't do it.

Using $array[1][2] is a giddy height I have yet to soar to. I was, however,
familiar with the $spludge[]; concept.

My solution was particularly shonky, I'm afraid.

  $read=fopen($file,"r");
  $count=0;

  while($read)
  {
  $x=fgets($read,512);
   if (!$x) { break; }
  $ctime=substr($x,0,2);
   for ($h=0; $h<=23; $h++)
   {
    if ($ctime==$h) { $calendar[$h].="$x\n"; }
   }
  $count++;
  }
 fclose($read);

Then later I split the file on "\n" and then again later (when I need the
information) on ":;".

Sorry. I'm not being obstenate by refusing to use databases; I just don't
want to get too far from the shallow end. Yet.

Thanks for your help.

James.
